摘要： PURPOSE: An encoding/decoding device and a method thereof for image data are provided to prevent the interference in the decoding by the lossy or hybrid compression after carrying out puzzle type coding for image data according to position information of the data, thereby preventing the data decoding if any exclusive decoder is not used. CONSTITUTION: A coding/decoding device for image data includes an image input part(210) for receiving digitalized image data or converting analog image data to digital image data, and a puzzle type encoder(220) for puzzling and encoding the image data input via the image input part by encoding keys, security keys, random number algorithm and the like. An image compression part(230) compresses the encoded image data by any one of lossy compression, lossless compression or hybrid compression. A compression releasing part(2430) releases the compression by carrying out the puzzle type encoding operation reversely. A reverse puzzle type decoding part(250) decodes the image data of which compression is released by using the encoding keys, the security keys, and the random number algorithm reversely. An image output part(260) outputs the decoded image data in the digital or analog form.
